Welcome to BrainBashers CalcuDoku. CalcuDoku are logic puzzles with very simple rules.

You can only access puzzles from the last ten days, so please choose a puzzle from below.

On Fridays, and during the weekend, you are treated to a large 9x9 puzzle, to keep you going that little bit longer.

Notes

Your task is to complete the grid such that every row and column contains every number exactly once, whilst at the same time making sure the cage clues are satisfied. Very similar to Killer Sudoku except it's addition, subtraction, multiplication and division.
